As I mentioned in the actual post what I mentioned were not cannon sources. I simply mentioned them to show that this is a trope that is still being used to this day. Also when I said it was still a trope I was referring to all media which is why I listed them in my post.
I don't really see how that works against me, if the Flash has never been pushed to run that fast before it further goes to show how badly he'd fair in a long distance run against the likes of Wonder Woman, Superman or Shazam. If your saying Superman was gassed the one time he was chasing after Wally and Barry do you not see how you've made the exact same argument you put to me. That could simple just be down the writer!
